Autonomous unit for growing indoor plants
Pluskal, Petr ; Appel, Martin (referee) ; Věchet, Stanislav (advisor)
This bachelor's thesis focuses on the design and assembly of an autonomous cultivation system for indoor plants in households. Autonomous and efficient cultivation of indoor plants poses a challenge for many home gardeners due to the constant need for care and attention. The thesis discusses the basic requirements and conditions for quality plant growth, such as temperature, soil moisture, air humidity, and lighting. Suitable sensors for measuring these key parameters are selected, and the thesis addresses their integration and implementation into the entire system. The unit's construction is realised using 3D printing, analysing its properties, particularly regarding waterproofing and contact with organic elements. These insights inform the printing of individual parts of the system. Combining printed parts, sensors, and a programmed Arduino system creates a functional autonomous plant cultivation system. Monitored data are directly utilised in the system's code, statistically processed, and visualised using the ThinkSpeak service. Experimental results demonstrate the successful functionality of the system in maintaining optimal conditions for plant growth and development. This autonomous cultivation system represents an innovative solution for simplifying the care of indoor plants in a home environment.

Computer-Controlled Planting
Pospíšil, Jan ; Šimek, Václav (referee) ; Růžička, Richard (advisor)
This work is focused on the issue of plant cultivation in domestic conditions. We focused on the automation of the growbox using the Wemos D1 R32 ESP32 board, which then consists of the design and implementation of three parts of the solution, i.e. the growbox itself, including the sensors needed to maintain ideal conditions for the plant being grown, the user applications, for interpreting the values and the configuration of the growbox. Application to collect data from growbox, for later analysis. The solution includes the creation of a demonstration growbox, software for all parts and comparison with available home growing systems.

LED light with adjustable spectral radiation for breeding and growing
Satora, Ondřej ; Hrach, Petr (referee) ; Klozar, Lukáš (advisor)
The aim of my master’s thesis is the design of the LED lighting system for breeding and growing purposes as replacement for the classical high-pressure sodium lamps and other sources of light used today. The whole system can be controlled locally by buttons or remotely by web server using Ethernet interface. LEDs are powered by five-channel step-down converter with current feedback. Converters are controlled by pulse width modulation generated by microcontroller.

Automatic greenhouse for growing plants
Paprsek, Adam ; Somer, Jakub (referee) ; Macháň, Ladislav (advisor)
The aim of this bachelor thesis is study the problems of automatic control greenhouse for growing plants and design concept of electronics. It focuses on possibilities of compensation of direct sunlight using artificial light sources, which has different wavelengths for the growth and flowering. Another function is to control humidity in the soil by watering. If the maximum humidity or temperature is reached to required values inside the greenhouse the fan will be switch on automatically. If the temperature falls under required limit, the green house will be possible to heat to achieve optimal adjustable temperature. The concept is designed to safe operate not only for the crew of greenhouse but for the cultivated plants also.

Integrovaná ochrana rostlin v akvaponických systémech
URBÁSEK, Jan
The aim of this bachelor thesis was to develop a literature search focused on the issue of integrated pest management (IPM) in aquaponics. Due to the fact that the literature focused on IPM in aquaponics is very limited, the work is based primarily on information about plant protection used in greenhouses or hydroponics. Individual methods of plant protection were evaluated based on their applicability in various types of aquaponic systems. The evaluation also considered their real usage in commercial aquaponic farming. Prevention is proving to be the most effective. By following strict preventive measures, more significant problems can be prevented. Subsequent resolution of the problems can be quite complicated and can cause irreversible economic losses on plant products. Chemical protection is now commonly used in plant protection in greenhouses and hydroponics. However, the application of chemical pesticides in aquaponics is highly problematic due to their possible toxicity to aquatic organisms. Due to the limited possibilities of using traditional chemical pesticides, it is therefore necessary to look for other alternatives. Natural products based on plant extracts could become one of these alternatives. There is a large number of plants that have pesticidal effect, but the possibility of their application is without further research very limited, as most products of plant origin have not been tested for their toxicity to aquatic organisms. In this work has been created an overview of plant products available on the market that could be used against problematic pests and diseases. Also based on literature sources there has been created a list of plants that can be recommended for future research into usability and inclusion in the IPM system of large aquaponic farms.

Hobby akvaponie
VONDRUŠKA, Vojtěch
The aim of this bachelor thesis was analysing hobby aquaponics systems available on the market and then designing, assembling and testing own aquaponics hobby system which can be used on balconies, terraces and gardens. Five different media beds and one combination of media bed and raft system were selected and evaluated. From the identified shortcoming of systems on the market were designed, assembled and tested in practice two media beds aquaponics systems. These systems were evaluated and compared with systems available on the market.

Tradiční a moderní způsoby přípravy osiva polních plodin
Necid, Václav
The bachelor thesis deals with the traditional and modern method of seed crop preparation. In the introduction of the thesis, the issue of seed production and its legal regulations is discussed, both at the level of the Czech Republic and in selected European countries. Agrotechnical differences are described in conventional and alternative seed production systems. Traditional and modern methods of seed treatment are described and their applicability and efficiency are evaluated on examples from agricultural practice. At the end of the thesis is described the research task. The aim of the research was to verify the effect of special treatment of seeds - plasma surface treatment and other seed treatments on germination and emergence of winter wheat (Triticum aestivum). The work uses professional books and magazines and available internet resources. The experiment was realized in the Laboratory of Molecular Genetics at the Department of Crop Science, Plant Breeding and Plant Medicine, AF MENDELU. In the experiment, seeds of winter wheat (variety Julie) treated with various variants of treatment were used. The germination rate determination results showed that K2 (Vitavax 2000 and TERRA-SORB foliar) had the highest germination percentage (98.75%), while P2 (low-temperature plasma and Vitavax 2000 and TERRA-SORB foliar and BlackJak) had the lowest germination percentage (88.75 %). Low-temperature plasma (LTP) treatment of seeds has no effect on the elimination of pathogens compared to variants where Vitavax 2000 was used.
